No Data Corruption & Data Integrity in Shared Web Hosting
We've tackled the problem of silent data corruption on our shared web hosting servers by using the amazing Z file system, or ZFS. The latter is superior to other file systems because it is the only one out there that checks all the files right away by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and regularly synced between them for redundancy. ZFS regularly examines the checksum of all files and in case any file is detected as corrupted, it's replaced immediately with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be copied on the rest of the SSDs. ZFS requires lots of physical memory to perform the real-time checks and the advantage of our cloud hosting platform is that we work with multiple very powerful servers working together. In case you host your Internet sites with us, your info will be undamaged no matter what.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you go for one of our semi-dedicated server solutions, you will not have to worry about silent data corruption because we use ZFS - a high level file system which checks all files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done immediately, so there will be no risk for any part of your content at any time. By comparison, other file systems carry out checks after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they are unable to detect silently corrupted files, so a bad copy may be replicated on the rest of the drives as well and you may lose critical data. Because this isn't the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
